(a) The top view of experimental setup. SG and IF represent the ICCD cameras for shadowgraphy and interferometry, respectively, WP is the Wollaston prism and PL is the polarizer. (b) Schematic view of the target design.
(a) The interferogram and (b) shadowgraph measured at . (c) The interferogram and (d) shadowgraph measured at . The horizontal coordinate and 4.5 mm are the surface of the first and second CH foils, respectively. Four beams were focused on the first CH at and . (e) The density profile measured at and . A large density jump is observed at . (f) The average intensity profile of (d) for .
The density profiles measured at (a) , (b) , and (c) . These profiles are calculated at the center of the target parallel to the symmetrical axis in each profile used for Abel inversion. (d) The position of given densities as a function of . Filled regions in above figures are the regions where the interference fringes cannot be observed and the density cannot be calculated.
The phase-space plots and corresponding ion density profiles at [(a) and (c)] and 2000 [(b) and (d)].
